Petrographic Description: Brian Mason

rules are abundant and varied in texture, and are set in a
fine-grained granular groundmass consisting largely of olivine and pyroxene.
Some of the pyroxene is polysynthetically twinned clinobronzite. Minor subequal
amounts of nickel-iron and troilite are present, in grains up to 0.5 mm across.
Minor weathering is indicated by brown limonitic staining around metal grains.
Microprobe analyses gave the following results: olivine, Fa24; Pyroxene, Fs21.
The meteorite is classified as an L4 chondrite.
